![]() Carpenter ant major and minor workers Carpenter ants, are very widespread. Here a major worker is shown on the left while a minor worker is shown on the right. The ants of this genus are often fairly large, measuring up to 3/4 of an inch in length." |
American
RoachThis is one of the largest of the common roaches found in the U.S. It often obtains a length of 1 1/2 inches. The American roach is a strong flier and both sexes have fully developed wings. Food storage and preparation areas, such as restaurants, grocery stores, bakeries, and houses, are often infested. The female roach can produce 6-14 egg capsules in one mating season. These capsules contain from 10 to 16 eggs each. Incubation for the eggs varies from 38 to 49 days, after which the young nymphs hatch. |

![]() Formosan subterranean termite soldier and alate The Formosan subterranean termite is a well-known invasive species in the Southeastern US. The soldiers can be distinguished from those of most local subterranean termites by the shape of the head, which is more rounded in Formosan soldiers. |

Sod
Web WormsThis is the most common caterpillar attacking turfgrass. They attack all grasses, but Bermuda is preferred and Bahia is least desirable. The larvae are greenish with numerous black spots and are 3/4" long when mature. Grass damaged by web worms has notches chewed along the sides of the blades or is eaten back unevenly. They feed only at night and rest in a curled position on the soil surface during the day. |
![]() Powderpost termite soldier and alate Powderpost termites are characterized by their soldiers' defense strategy. The soldiers use there heads to block up tunnels from hostile intrusions. Powderpost termites are closely related to drywood termites. |

![]() Old house borer The old house borer, Hylotrupes bajulus, can cause severe damage to wood. Distinguishing features include the antennae, relatively short for cerambycid beetles, and the significant dorsoventral flattening. |
SilverfishUnlike the firebrat this bright silvery cousin prefers cooler, more moist areas. Its diet is similar to the firebrat's. Since it does not like dryness or heat, it is less likely to be found in the heated home in the winter. At the optimum temperature of 72-80 degrees F., the females may lay up to 100 eggs in a lifetime. The life cycle may be completed in 3 to 4 months, but usually longer periods are required. |
MealybugsThese are soft-bodied insects covered with white, powdery or cottony, waxlike material. Short wax projections extend from the margin of the body and some species have long filaments projecting from the rear of the body. They vary from 1/8" to 1/5" in length when mature. Mealybugs have piercing-sucking mouthparts and damage appears as chlorotic spots on the leaves. They tend to congregate together, looking like fluffs of cotton on the foliage. The life cycle takes about 30 days at 80°F. |
![]() Dampwood termite soldier Dampwood termites are closely related to drywood termites. However, they are more primitive in habit and appearance. They tend to be larger as well. The soldiers share the trait of toothed mandibles. |
Oriental
RoachThe photo shows the jet black wingless nymph. This roach is often referred to as the sewer roach, as it is found in sewers and in buildings with damp basements. It often climbs water pipes and enters upper floors of buildings. The oriental roach is gregarious and lives in colonies. Females may deposit up to 18 egg capsules (ootheca) usually containing 16 eggs. |
Aphidsare soft-bodied, pear-shaped insects. They are generally less than 1/8" long and are usually green, but many aphids are black, brown, pink, yellow or blue. Aphids are commonly found on young, developing leaves and stems in clusters or colonies of individuals. Their feeding distorts a plant's new growth, and the leaves curl. Most aphids are wingless, but when colonies become overcrowded, winged forms are produced. |
![]() Subterranean and powderpost termite workers Shown here are workers of two different termite families. At the top is a worker, a subterranean termite. Below is a worker of a powderpost termite. Note the larger legs, hairier body and more well-developed antennae in the subterranean worker. These features correlate with the more active foraging style of subterranean termites. |

![]() Eastern subterranean termite soldier and alate The eastern subterranean termite, Reticulitermes flavipes, is one of the foremost wood-destroying insects in the US. Native subterranean termites tend to have very dark alates and soldiers with rectangular heads. The soldiers of subterranean termites are characterized by toothless, sickle-shaped mandibles and a pronotum narrower than the head. |

![]() Carpenter bees The carpenter bees of the family Anthophoridae resemble bumblebees in size and appearance. However, the abdomens of carpenter bees are largely bare while those of bumblebees are hairy. Note the well-developed jaws for wood excavation. Although not particularly aggressive, these bees do have well-developed stingers (see lower right), and should be treated with caution. |
